全局游戏控制器
var gameMaster;

}
键盘事件handler
document.onkeydown = function (){
var key = document.all ? event.keyCode : arguments[0].keyCode;
left
if(key == 37){
}
up
else if(key == 38){
}
right
else if(key == 39){
}
//down
else if(key == 40){
}
}
连续按键时使用
document.onkeyup = function(){
var key = document.all ? event.keyCode : arguments[0].keyCode;
if(key == 37 || key == 38 || key == 39 ||key == 40){
isKeyBoardMoving = false;
}
}
鼠标事件
document.οnclick=function(e){
如果是左键
if (e.button == 0){
// clickX = Math.round(e.clientX/10) * 10;
// clickY = Math.round(e.clientY/10) * 10;
}
}

返回客户端对象
function $(clientId){
return document.getElementById(clientId);
}
获得SELECT选中项
function GetSelectObj(clientId){
var obj = $(clientId);
var index = obj.selectedIndex; // 选中索引
return obj.options[index];
}
生产随机数
function GetRandom(n){return Math.floor(Math.random()*n+1)}
存储键值对
function addKV(k,v){
localStorage.setItem(k,v);
}
取得键值对的值
function getV(k){
return localStorage.getItem(k);
}
获得本地存储的所有值并转化为字符串
function getAllValueToStr(){
var content = "";
for(var i=0;i<localStorage.length;i++){
//key(i)获得相应的键，再用getItem()方法获得对应的值
content += localStorage.key(i)+ " : " + localStorage.getItem(localStorage.key(i)) + "<br />";
}
return content;
}
显示当前时间
function GetCurrentDateTime(){
var time ;
with(new Date()){
time =toLocaleString() + '星期' + '日一二三四五六'.charAt(getDay());
}
return time;
}
